Virtual Assembly System Design

Assembly design is an important stage in product design process , and it exerts signigicant influences on product' s cost,quality and time_to_market . In the early of design .virtual assembly techniques will concern the problem about assembly and assembly cost and so on. Thus .virtual assembly can shorten the time and cost of design .Based on the UG software ,this paper makes a deep research in virtual assembly' s architecture .realization and key techniques .Main work of the research was as follow:(1) Establish a reasonable structure of virtual assembly system and clarify the interrelation of each component by means of analyzing the information content of product assembly model which holds the whole product assembly information.(2) Establish the implement method of a part' s 3D constrained movement based on movement freedom in virtual environment.(3) Proposed a new algorithm of assembly sequences planning which has reduced the complexity and has solved the problem of large_scale assembly sequences generation .In addition , the code written in c language was given . Base on this ,you can get a more practical algorithm by adding several constraint condition in according to your request .(4) Present some development skills after studying hard on further development on UG software in_depth .(5) Establish a basic structure of virtual assembly process system.,...
